WHEEL-HUB.

I Specification of Letters Patent. Patented Kitty 18, 1915.

Application filed August 26, 1911. Serial No; 546,227.

To all whom it may concern: I I

Be it known that we, WALTER P. Horwoon and PHILIP H. Kuon, citizens of the United States, residing at Baltimore, in the State ofMaryland, have invented a new and use ful WVheel-Hub, and we do hereby declare the following to be a full, clear, and exact description of the invention, such as. Wlll enable others skilled "in the art to which it appertains to make and use thesame.

This invention relates to a new and useful hub construction for wagonwheels.

The main object of the invention is to' iniprove and simplify theg'eneral construction of wheel hubs. i

A further object of the invention is to provide a hub including several sections, and provided with means for locking the sections together about a body of the hub.

The invention comprises further features and combination of parts as hereinafter set forth, shown in the drawings and claimed.

In the drawings:Figure 1 is a view in the elevation of the hub, showing the back o section thereof removed, and disposed in a position ready to be fitted on the hub, showing the locking means between it and the hub. Fig. 2 is a longitudinal sectional view through the hub. Fig. 3- is a view on line 3-3 of Fig. 2.

Referring more particularly to the drawings 1 designates the central bodymember having the usual inner metal bearing sleeve. The body member may be madeof any suitable material but in the present instance, the same is constructed of wood or similar fiber. Adjacent the inner end of the body member, an annular shoulder is provided, designated by the character 2. Fitting telescopically over the body member, and in contact with the shoulder 2 isthe central sleeve section 3, in which the spokes 4; of the hub are secured, as shown at 4E. The. central sleeve section, at each peripheral edge thereof, is provided with annular grooves 5 and 6.

central section of the hub, as shown at 12. Between the shoulders 10 and 11 annular bulges 13 are formed, which contact with the bevel By these shoulders a Wedge connection is maintained between the sleeve 9 and the body of the hub, there being an enlargementof white lead or other cement between the bulges 13, to assist in holding the sleeve 9 in place. The portion 14 of the metallic sleeve 9 beyond the shoulder 10 fits into the annulargroove 6, there being a deposit of white. lead, or other cement or plas' tic material arranged in the groove,.for holding the sleeve 9 to the central-section. By theprov1s1on of the annular bulges of the sleeve 9, and the enlargement of white lead or other cement, the sleeve 9 is held'in place. The sleeve 15 fits telescopically over the inner end of the body member, with the portion 16 thereof fitted and cemented by white leader other plastic material into the groove '5, asshown in the drawings. The sleeve 15 approximately fits the bevel 18 of the hub, there being a deposit of white'lead or other plastic material 17 arranged between the sleeve 15, and the bevel 18, so as to assist in holding the sleeve 15 in position. The inner end of the body or hub is provided with short longitudinal grooves 19, which are adj oined by the lateral portions 20. The sleeve 15'is forced on the body or hub, by ten to forty ton pressure. When the sleeve 15 is forced on the body, the lugs 21 cut the grooves 19 to hold the sleeve 15 on the hub member; By this arrangement, in combina tion with the deposit of plastic material 17, the sleeve 15 is held securely in place. The spokes which are arranged in the central section extend partially into the body member of the hub, asshown at 22.

From the foregoing it will be noted that there has been produced a simple, novel, and

efficient hub construction, and one which has been found to be practical.

The invention having been set is claimed as new and useful is 1. In combination, a hub member, a cenforth, what tral hub sleeve section on the hub member and spaced apart therefrom including a deposit of white lead therebetween, said central hub sleeve section having an annular groove at each end, a sleeve fitting the outer end of the hub member and seated inone of the grooves of the central hub section, an enlargement of white lead between the hub member and the outer sleeve, an inner sleeve seated inthe other groove of the centralhub section, deposits of hite lead in said grooves to seal the inner and outer sleeves to v 1 Copiesbf thi s patent maybe obtained for five cents each, by addressing the Commissioner of Patents.

j the central hub section, the central hub sec-s tion having radial tapering openings, the hub member having recesses registering With 1 ,saido'penings, and spokes corresponding in shape to fit said openings and said recesses, thereby constituting means to hold the central hub section spaced apart equally from the hub member, so that the deposit of White'lead may be arranged in the hubsection and hub member When assembling such parts.

2. In combination, a hub member, a cen tral hub sleeve section on the hub member.

and spaced apart therefrom including a deposit of White lead therebetweemsaicl centra l hub'sleeve section having radial tapering openings, the hub member having re cesses registering With said opening, spokes having their inner ends shaped to fit'the 'member, so that the deposit of White lead may bearranged between the hub sleeve section and the hub member When assembling such parts, and sleeves, one secured to each end of the hub member and being secured to the central hub sleeve section to hold the central sectionin place;

In testimony whereof We have signed our names to this specification in the of two subscribing Witnesses.
